Webpage using significant energy / memory on Mac

All the reponses here to get rid of the problem are temporary at best and most are just plain useless not helpful sorry. I know the intentions to have a work around are good but this is an Apple created problem and needs to be addressed by their software engineers. I have been in the genius bar twice and called Apple support twice and still no resolution even with a senior advisor. Very sad how unresponsive Apple is for the price we are paying for these MACs. Let's see if this even gets posted as Apple has censored my other posts for not giving any technical advice. So here is my technical advice folks: use Chrome web browser and wait for a software update (you could be waiting a very, very long time).

After reading the initials posts about this problem, at least on this thread, dating back to April of 2018, I skipped to the last page and found the apparent answer that Apple has ceased to support things the rest of the world continues to support "in the name of progress". Great. Same thing with the forced usage of USB-C, right? Are they making a conscious effort to drive people away from their platform, oh "in the name of progress", of course? I guess I'm a legacy person living in a progressive world (which, BTW, is not obliged to be Apple-centric).

Hmm let me see Safari is working on my behalf? Sorry I know you're trying to help but I don't think so and the following comments are directed to Apple Corp so nothing personal.

Hey Tim - do you seriously think my brand new >$2k Mac should constantly give me a warning "This webpage is using significant energy. Closing it may improve the responsiveness of your Mac" for playing NETFLIX??????

WHY DON'T YOUR SOFTWARE ENGINEERS improve the responsiveness of my Mac!!!!!!!!!!!!

This is a total Apple issue that I can buy a cheap no-name brand laptop and watch Netflix with NO PROBLEM but my MacBook Pro (PRO!) cannot handle Netflix and there is absolutely no way to turn this annoying message OFF!!!!!!

Focus on performance and have your software team fix all these issues (including flickering video watching Netflix on Safari) with a software update (for the amount of money we pay you would think an Apple software engineer could respond to these forums and at the very least say they will look into it).

I always get this error especially when I am on my yahoo page. It does not come up when I am on Google. It's annoying and it slows down browsing. I never had this before Steve Jobs RIP. This company slowly not what it used to be. :(

This issue has been going on and on, and it's highly annoying. Apple please fix this nonsense with your OpenGL support. I spent 5 grand on an iMac Pro and have this issue, and between the bitrate issue with the audio and this annoying openGL issue, which happens predominantly with Safari, it's highly irritating. FIX YOUR SH#$

Agreed! Ever since I updated the software, I get this error message. I thought it was Apple's way of getting me to buy a new computer... Apple I've been a customer since 2000 but the quality of your products just isn't the same. Can you please get it together?

I'm not sure if anyone is still following this conversation but I am constantly getting the messages this page is using significant energy or memory. It started after installing the new operating system and got significantly worse after just installing a new update just today. What can be done about this? I am pretty sure it has something to do with the new operating system.

Let me just say I miss Steve Jobs :(

While many did not appreciate him so much as a person. I can say he always made sure his products matched the price. He absolutely cared about his product, and those who paid for it. I have up until recent been a huge fan of Apple computers especially to support my music projects.

My system is up in age a bit but, not so old that it is part of the problem. Many apple purchasers have this complaint. So, if at some point the current Apple generation decides to up their game on the quality of it's products. I for one will continue to work on my older system until it breaks, and purchase another product outside of Apple because of their lack of care and responsiveness. I too got the same response of them not taking accountability for fixing this issue or at least admitting the cause. I also agree for the cost of their products to disregard customers is ridiculous about system issues.

Yeah,

so everyone who is trying to find fix for this just reply to this thread, maybe apple really will add option to this where user can accept that some sites just uses memory...

there is ofcourse another fix to this, start using chrome.. and I am seriously thinking about this..

It seams like that the only way we can be free for that to pop up all the time is to install Chrome on the machine.. Safari should have made an option where we can select our self if we want that warning or not.. If we play online game or stream movies then we are fully aware that we use a lot of memory so we don't need to be reminded every few minutes about that.. It's just annoying. And make people use Chrome instead.

I just recently switched to Safari after using Chrome for the last 9 years. I made the switch for 2 main reasons; 1. Privacy. 2. Performance of my MacBook Pro. I had read that Mac's get better performance and battery life by using native apps. Getting this message kind of makes it seem like the opposite is true. Really confused by this and surprised Apple has not at the least addressed the issue or explained why it does this?

Same here. This began fairly recently. I have no Safari extensions, I have no apps that didn't come from the App Store. i have no keepers or cleaners and my etrecheck showed that my mac performance was excellent. I usually get this message when I'm on CNN or CBS and there is a video accompanying the news story. I've never had this before. I've been thinking I was hacked but obviously others here are experiencing this too.

I have recently purchased a new iMac 27". It replaces a 2014 Mac mini. I, too, continue to get that "warning", especially on Facebook. I never saw it on my Mini at all which was running the same OS and all else being equal. What would make the new machine do this I've wondered. I even called support and they were not able to assist at all. Now I see I'm actually not the only one with this issue which, at least, makes me feel a bit better....LOL. I've tried everything, resetting, running "First Aid" from Utilities, checking resolution, etc. and it still shows up. Seems to be only with Safari, not with Firefox. Hoping to see some response from someone who has come up with some type of reasonable explanation.

Safari ... Other than the annoying message and one of my G5 games constantly crashing

I have been researching this issue and the useless "annoying" message, digging around in the Developer site, asking questions and getting zero response. So far I have turned up nothing.

An experimental feature(?) New WebKit Features in Safari 11.1 | WebKit

I realise that it only happens when opening Facebook on Safari. No problems with other webpages. Not sure if this is a problem with the Facebook webpage or Safari browser. So far nobody has a satisfying answer to this problem. Frustrating!!
